Prep: Cook rice and chop vegetables and pita for serving. Set aside.
Marinate the chicken: In a medium bowl, add olive oil, lemon juice, oregano, garlic, salt and pepper. Whisk with a fork. Add chicken, toss to coat evenly, cover and refrigerate until ready to cook. The longer you marinate, the deeper the flavor.
Make tzatziki sauce: Place grated cucumber in the center of a cheesecloth or linen kitchen towel, twist into a ball and squeeze very well until dry. In a medium bowl, add squeezed cucumber, Greek yogurt, lemon juice, olive oil, dill, garlic, salt and pepper. Stir well, cover and refrigerate.
Cook the Greek chicken: Preheat large non-stick skillet on medium heat and add 1 tablespoon of oil. Add chicken, cook for 5 minutes per side or until thermometer inserted in the center registers 165F. Transfer to a cutting board, let rest covered for 10 minutes and cut into bite-sized pieces.
Assemble the Bowls: To serve, in each bowl place cooked rice, chicken, cucumbers, tomatoes, olives and red onion. Sprinkle with feta cheese and add generous dollop of tzatziki, pita bread and a lemon wedge. You can add whatever else you like. Enjoy!
Notes
You will have at least half of tzatziki sauce leftover. Only 1 cup of sauce is included in nutrition calculations. Refrigerate the rest in airtight container for up to 7-10 days.
